The ? shape in the figure below is shown using 9 pixels in a 3 × 3 grid. The color levels are given to the right of the figure. Use the matrix 
that represents a digital photograph of the ? shape to solve the problem.
Using the same color levels from the instructions, write a 3 × 3 matrix A that represents the letter L in dark grey on a white background. Then find a 3 × 3 matrix B so that A + B lightens only the letter L from dark grey to light grey.
